Which is kinda my point. The amount of HD traffic and wasted bandwidth is just insane. At what point would YT just acknowledge the same viewer is watching (or listening) the same video over and over and over again before offering a download button? (sure tech ppl can use 3rd-party tool, but all are blocked on Google Play, and most others limited to short vids only)
Anything that wastes bandwidth, I see as a positive thing because it's pressure on networks to increase bandwidth. Once it's in place, using it is harmless since it would otherwise have been wasted serving nobody. Netflix forced ISPs in my country to pull finger when their customers would have regular evening internet slowdowns. I'm looking forward to more improvements as they cater to cloud gaming.
